3. Wait for the completion of the pairing (remaining seconds is 0). If pairing fails, an
error is displayed. In this case, repeat the pairing steps. If the problem persists,
contact SolarEdge Support. When pairing succeeds, the following message is
displayed:
P a i r i n g
P a i r i n g C o m p l e t e d
Upon pairing completion, the inverter continues with assigning numbers to the
power optimizers and mapping them into strings:
Power optimizer detection - the power optimizer IDs are detected and each
optimizer is assigned a unique number, which is later used by the inverter for
synchronizing telemetries. This detection is performed while the optimizers are in
safe voltage .
String detection - During this procedure the logical string of each optimizer is
detected. This detection is performed while some optimizers are set to MaxVout
mode.
The detection and assignment of power optimizers may take up to 2 minutes.
The system startup process begins:
Since the SMI is ON, the power optimizers start producing power .
WARNING!
When you turn ON the SMI ON/OFF switch, the DC cables carry a high voltage
and the power optimizers no longer output a safe 1V output.
Step 3: Verifying Proper Activation
After pairing, a status screen similar to the following appears on the SMI LCD panel:
V d c [ V ] I d c [ A ] P d c [ W ]
4 3 0 . 1 2 6 . 1 1 1 2 3 4
P _ O K : 0 8 0 / 0 8 0 O N
1. Verify the following:
The green SMI LED is steadily lit.
The ON/OFF indicator on the LCD panel reads ON.
P_OK: XXX/YYY: There is a connection to the power optimizers and at least one
power optimizer is sending monitoring data. Optimizers send telemetries in a
frequency of up to 10 minutes. Initially after pairing, both XXX and YYY values
show 000 and the values increase as paired poweroptimizers are reported.
